 thickened. Intermediate femur equal in length to the tildae, tarsus, and claw

MICRONECTA ANNAE Kirk., var. PALLIDA Kirk. 



Micronccid (itiiuiv Kirk., var. pdllidti Kirk.. P.L.S., N.S. Wales, xxxii, li)()8, p. 788. 



"No transverse line on pronotmn ; tegmina with a ])ale castaneous l)a.sal 

 l)and. Hab. Q. : Kuranda (Ang. ; Perkins)." 



The characters constitnting the ^-arietal diagnosis as given by the author are 

 variable in some other of the s]iecies examined by me; the distinction of a 

 "variety"' on such foundation alone is somewhat doubtful. 



MICRONECTA MICRA Kirkaldy. 



MIcroneeta micnt Kii-k., P.L.S., X.S. Wales, xxxii, 1908, ]). 788. 



"Pale broAvn, bi'ownish-testaceous beneath; a pale castaneous l)and at the 

 base of the tegmina, lateral margins with one or two dark specks. Abdomen 

 above partly dark. Head well rounded in front of eyes, which are practically 

 contiguons with the corium. Pronotum very short, narrower than the head, 

 hind margin fnnwdtf. Length, 2 mill. Hab. Q. : Kuranda (Ang.; Perkins)." 



The main distinguishing feature of this small species appears to be the short, 

 narrow, and posteriorly truncated pronotnm. 



DIAPREPOCORIS Kirkaldy. 



Diapirpocoris Kirk., Ann. Mag. Nat. Hist, (b), xx, 1897, p. 7)2. 



Type, D. harycephala Kirk. 



This monotypic genus was founded upon female specimens. The palae, 

 Vhich are similar in both sexes, are "Idsegmentate, " the terminal joint having 

 Ihc form of a strong claw. Kirkaldy remarks that the "second segment appears 

 to be a genuine second tarsal segment, not a single claw." The abdominal seg- 

 ments of the male ai-e not disordered 1o the same extent as in other genera of 

 Corixidae, and the asymmetry is not evident on the nnderside. The antennae 

 arQ four-jointed (fig. 350a), and neither sex has a facial impression.
